CHARLES DANFORII-I, OF PATERSON, NEWY JERSEY,

MODE 0F DRIVING BOBBINS IN CAP-SPINNERS.

To all 'whom t may concern.'

Be it known that I, CHARLES DANFon'rI-I, ot Paterson, in theA county ot Passaic and State ot New Jersey, have invented a new and usetul Improvement in the Method ot Driving Bobbins in the Spinning-Machine Commonly Called the Dantorth Frame or Cap Spinners, ot which the tollowing is a tull and exact description.

The drawings hereunto annexed and which I desiremay constitute a part ot this specivtication consist ot seven parts and are as tolw lows, viz:

Figure l is a horizontal section ot the machine (halt length) exhibiting the mode ot working the litters, together with the main shatt, &c. Fig. 2 is a ground or horizontal view ot the litters, cross bars, drums, tension pulley, band direction pulleys, drum band pulley and band. Fig. 3 is a ground view ot one ot the drums showing the mode ot banding to drive the wharves, tubes and bobbins. Fig. 4t is a transverse section through the machine atthe center ot a drum exhibiting' the lifting operation together with the counter-balance weight one ot which is placed at each end ot the machine. Fig. 5 is a tront elevation View ot the machine showing one drum banded ott complete together with the spindles, wharves, bobbins, caps, and rollers. Fig. 6 is an. elevation view ot the ground end ot the 1na chine. All the above figures are drawn to a scale ot one and a halt inch to the toot. Fig. 'Y is an isometrical view showing the mode ot banding the drums, wharves, &c.

All the letters and characters in all the figures reter to the same parts ot the machine.

In the first place the trame work ot the machine should be so constructed that the spindle rails A, A and roller beams B, B on one side ot the trame will be about one inch and three-quarters higher than they are on the other side. The traverse rails or litters C, C may be worked by any ot the twelve inches in diameter by means ot an endless hand F, the pulley E is fixed to the outer end ot the mangle pinion shatt G on the inner end ot which is a pinion H ot tour teeth working into the mangle wheel I which is fastened to the mangle shatt J on each end ot which is a bevel pinion K K about tour inches in diameter containing thirty-two teeth, these gear into two other bevel wheels L L containing itty-siX'teeth each, which are fixed to the litter` shatts M M on which are tastened spur pinions N, N, N, N which are one and tive-eights inches in diameter to their pitch line and contain twenty-six teeth each. These gear into racks on the back side ot litter rods O, C, O, O, on the tops ot which the litters C, C are fixed. It will be perceived that by this arrangement the litters on both sides `ot the machine are inad-e to rise at once and tall at once by which it is necessary to use two counterbalance weights P, P one at each end ot the machine. These are suspended by chains trom pulleys Q., Q, Q, Q about tour inches in diameter which are fixed to the litter shatts M M. It will be perceived that this mode ot traversing the litters is the same as that described in the specification ot a patent granted to me on the tourth day ot May, A.. D. one thousand eight hundred and torty-one with the exception ot gearing the bevel wheels so as to make the litters rise on bothsides ot the machine at once as atoresaid instead ot rising on one side while they are talling on the other.

In the next place the horizontal cylinder commonly made use ot tor giving motion to the wharves, tubes, and bobbins is dispensed with and in its stead I make use ot uprighttin drums R, It, It, It, R, similar to those used in mules. The-y are about twelve inches in diameter having two grooves termed in them at or near their upper ends tor the band to run in by which they are driven. These drums are supported by cross bars S, S, S, S, S passing trom one litter to the other to which they are bolted so that the drums are made to rise and tall with the litters. The top bearings ot the drums are supported by brackets T, T which are bolted by flanges to the cross bars S, S, &c. Mo-

tion is communicated to the drums by means ot an endless band or cord U about the size ot a mule drum band, leading around the lower periphery ot a grooved pulley V about eighteen inches in diameter having a. strip groove turned vin its surface to take hold on vof the iirst drum, passing round which it leads to the lower groove of the fourth drum, from thence to the upper groove of the third drum, from thence to the upper groove of the sixth drum, passing round which it leads von the lower groove of the iifth drum, from thence it leads to a tension pulley X this pulley is about fourteen inches in diameter', has a groove in its surface for the band to run in, from this pulley the band leads in a line nearly parallel with the machine to direction pulley Y passing over the top of which it leads on to pulley V the place of beginning. The direction pulleys,

IV and Y run on center' pins or studs which are supported by brackets bolted to the frame end.

The tension pulley X runs on a stud or center pin which is fastened by a screw and nut in a slot formed in cross bar Z, this cross bar is fastened to the lifters U, C and together with the tension pulley which it carries rises and falls with them so as to keep the pulley always level wit-h the drums. The slot in the cross bar Z is made for the purpose of sliding the stud which carries the tension pulley for the purpose of regulating the tension of the band.

The grooved pulley V is fixed to the main shaft a. This shaft is supported at its inner end by a plumber block Z) which is fastened to a cross bar c, running across the frame and bolted by flanges at its ends to the arches. The outer end of the shaft a is supported by a bracket l which is bolted to the frame end.

c is a pulley on the main shaft t which gives motion to pulley by means of a strap and thus motion is communicated to the rollers.

g, g are the fast and loose pulleys on which the main belt runs and gives motion to the whole machine.

I make some of the drums drive twenty bobbins and others twenty four according to the number of spindles I wish to put in a machine and apply that number to each drum may mcst evenly and conveniently divide the-whole number. The drum represented as banded oif in the drawings has twenty bobbins attached to it, ten on each side of the machine. The whole length of the tubes I), is six inches to which the wharves are attached and constitute a part of the same piece of metal. The wharves z', e', c', z', i are placed on the tubes Z), Z), &c., at different distances from their lower ends one above another similar to the arrangement of mule wharves on the spindles so that the bands may clear each other as well as the wharves that they do not drive. The lowest wharve is five eighths of an inch from the bottom of the tube and the highest one is one inch and seven eighths, the intermediate ones rising one fourth of an inch as you advance from the lowest to the highest.

There are two tubes with wharves of each height on each side of the machine to each drum and each of the small bands y', j, j, j, drives two wharves, tubes and bobbins.

I have described each drum as driving twenty or twenty four bobbins, but it is obvious that the number may be varied so as to drive more or less by putting in more or less drums without varying the principle of the machine. The height of the wharves may also be so arranged as to band each wharve with a separate band.

As the wharves are not all of one height, I put blocks of wood 7c, le, 70, 7c, f: on the tubes for the bobbins to set on about one inch in diameter and of a sufficient length to bring their tops on a level with the top of the highest wharf which has no wood on it. rIhe same end may be effected by casting or fixing metal buttons or blocks on the tubes to sustain the bobbins.

I have described the drums as traversing with the lifters but I sometimes use them static-nary in which case they are made of sufficient length to admit the bands that drive the wharves to t-raverse up and down yon them and are supported at their bottoms by cross bars running from one spindle rail to the other to which they are bolted instead of being fastenedA to the lifters, as described above and at their tops by cross bars fastened to the roller beams.

What I claim as my invention, and desire v to secure by Letters Patent, is- Y The combination of t-he tubes (on which wharves are affixed at different heights), with the blocks or buttons (7c) placed thereon for the purpose of supporting the bobbins at the same height, the whole constructed in the manner, and for the purpose herein set forth.
